Description
Invention field
The present invention relates to a kind of method that realizes network management system, especially relate to a kind of method that realizes the cable TV network network management system.
Background technology
Along with the development and the development of technology of society, the application of cable TV network is more and more widely more and more goed deep among the huge numbers of families.Accordingly, the technology of relevant cable TV network is also constantly progressive, and along with the continuous development of network and perfect, improve gradually the status of network management system.
But the network management system of existing cable TV network all is based on and makes up on the analogue technique, has various shortcoming.Mainly being can not be rapidly, accurately the misoperation of equipment on the network is reported to the police, and more is difficult to accomplish Realtime Alerts, can not repair as early as possible thereby cause when certain equipment operation is unusual on the cable TV network; Accuracy to which or which parameter is reported to the police, this parameter is present numerical value of the particulars of warning spot, this equipment etc. is relatively poor; And the front-end control facilities of different manufacturers (HEC) can not be compatible, causes reducing of choice, increased network cost.
U.S. CATV Project Shi Xiehui (SCTE) has worked out the fiber optic cables net management sublayer committee (HMS) webmaster standard, and this standard is intended in the open system framework, the interoperability of the network management responder of promotion cable TV network and the development of plug and play.Because the HMS standard has standardization, opens opening, the characteristics of interoperability and plug and play, the front-end control facilities (HEC) that the transponder of HMS standard can compatible any producer provides, the interface of having unified transponder, make these transponders all use identical agreement, therefore increased the choice of network monitoring, network operation and network management greatly, reduced network cost, this standard can also be simplified the operation of cable TV network simultaneously, improving service quality, is the developing direction of cable TV network network management system therefore.
Summary of the invention
The objective of the invention is: propose a kind of method that realizes the cable TV network network management system, and this network management system is based on the one fiber optic cables net management sublayer committee (SCTE-HMS) of cable communication engineer committee standard, adopt digital technology, can provide real time data to the network management personnel to the misoperation of equipment on the regular maintenance of cable TV network and the network, and can carry out monitoring management headend equipment.
The object of the present invention is achieved like this: a kind of method that realizes the cable TV network network management system may further comprise the steps:
A) on the equipment that in the cable TV fiber optic network, needs to monitor transponder is set, utilizes the transponder that is directly connected on this equipment to read the monitoring data of this equipment;
B) in advance to the fixing ID address of each apparatus settings on the above-mentioned cable TV fiber optic network;
C) on above-mentioned cable TV fiber optic network, some channels are set to up channel and down channel respectively in advance;
D) utilize that device data is uploaded to above-mentioned cable TV fiber optic network network management center on the network that above-mentioned up channel obtains each above-mentioned transponder;
E) above-mentioned cable TV fiber optic network network management center analyzes the above-mentioned data of uploading, and judges according to predefined data area whether the above-mentioned data of uploading are unusual;
F) above-mentioned cable TV fiber optic network network management center judges unusual equipment and unusual parameter and warning to abnormal data according to the ID address;
G) above-mentioned cable TV fiber optic network network management center reaches headend equipment according to instruction and by above-mentioned down channel.
And,
Above-mentioned transponder is built in the equipment of above-mentioned needs supervision.
Above-mentioned transponder is connected on outward in the equipment of above-mentioned needs supervision.
It is 6MHz that above-mentioned down channel is provided with bandwidth.
It is 4MHz that above-mentioned up channel is provided with bandwidth.
Above-mentioned down channel is provided with 19 altogether, and frequency is from 48MHz to 162MHz.
Above-mentioned up channel is provided with 4 altogether, and frequency is from 5MHz to 21MHz.
The byte of the data of transmitting in above-mentioned up channel and the above-mentioned down channel adopts 10 bits, comprises eight data bit and beginnings, stops flag bit.
Each state predetermined fixed one up channel and down channel to above-mentioned cable TV fiber optic network.
By above-mentioned technical scheme, just can realize purpose of the present invention.Utilize transponder directly from the cable TV fiber optic network equipment obtain equipment operating data, again by a plurality of up channels with data upload to network management center, because each equipment all has fixing address on the network, therefore when if network management center finds one or several abnormal parameters in certain data, can determine it specifically is that equipment immediately, accomplish real-time monitoring, make things convenient for the running status of network management personnel from far-end monitoring fiber network.Simultaneously, the network management personnel can finish network management task by network management center by the move instruction of down channel forward end.Simultaneously, above-mentioned technical scheme meets the cable communication engineer committee-fiber optic cables net management sublayer committee (SCTE-HMS) standard
Description of drawings
Fig. 1 is the schematic flow sheet of method of the present invention.
Embodiment
Describe preferred embodiment of the present invention in detail below in conjunction with accompanying drawing,, can more clearly find out advantage of the present invention place by description to preferred embodiment.
As Fig. 1, at first be step s10, in the cable TV fiber optic network, on each equipment that needs to monitor transponder is set, transponder is directly connected on the equipment that is monitored, and transponder adopts the method that is built on the equipment of being monitored; Then be step s12, to the fixing ID address of moving on the fiber optic network of each apparatus settings; Be step s14 again, 48MHz is set to the data downstream channel to 162MHz in the bandwidth, is provided with 19 altogether, the wide 6MHz of each channel; Next be step s16,5MHz is set to the data uplink channel to 21MHz in the bandwidth, the wide 4MHz of each channel.
Be step s18 below, be built in after transponder on the equipment that need to monitor obtains the service data of equipment, transmit to the network mesh tube hub by up channel.The data byte that transmits adopts 10 bits, comprises 8 data bit and beginnings, stops flag bit.Then be step s20, network management center analyzes the data that receive, and compares the predefined data range of normal value of each equipment, has judged whether that equipment operation is unusual in the fiber optic network, and concrete that and that Several Parameters of operation exception are unusual, and report to the police.Be step s22 at last, the webmaster personnel according to circumstances assign instruction and are sent to headend equipment to repair misoperation by down channel, and wherein the downlink data byte also adopts 10 bits, equally also comprises 8 data bit and beginnings, stops flag bit; Perhaps the webmaster personnel go out to repair operation.
In transfer of data, each byte is always transmitted the least significant bit behind the start bit earlier; And in multibyte field, then be to transmit most significant byte earlier, transmit least significant byte at last.
Can all fix a up channel and down channel in advance to transmit data to each state of cable TV fiber optic network, so just can carry out single management carrier frequency.
In step s10 and step s18, described transponder also can be connected on outward on the equipment that needs to monitor in the cable TV fiber optic network.
Here it is pointed out that according to essence of the present invention those of ordinary skill in the art can make various suitable distortion or replacement on basis of the present invention, but all these distortion or replacement all should belong to protection scope of the present invention.
